Which radars cover Chapman?
The closest NEXRAD Doppler radar is KDIX (Philadelphia, NJ), about 77 miles southeast. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Chapman | View |
|---|---|---|---|
| KDIX Philadelphia, NJ | 77 mi southeast | 6,500 ft | Fair — the beam can pass over shallow snow and low-level rotation |
| KBGM Binghamton, NY | 104 mi north-northwest | 10,200 ft | Limited — the beam overshoots the lowest part of storms |
| KOKX Upton, NY | 133 mi east | 14,900 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
